PLOW.

EPECfFIGATIOhL forming part of Letters Patent No. 282,999, dated August14,1883.

Application filed May 2, 1883. (No model.)

ments in plows, hereinafter specifically designated by the claims,including devices for preventing clogging or choking, for turning un derweeds, &c., for turning-or jointing the edges of the furrow-slices, sothat contiguous edges of adjacent slices shall not injuriously lap, forattaching a pole to the plow-beam, for connecting a riding attachment tothe plow and providing for its adjustment, and for placing the plowthoroughly under the control of the attendant.

In the accompanying drawings of my dim-v provements, Figure 1 1s a viewin elevation as seen from theouter or mold-board side, a portion of thetongue being broken away. Fig. 2 is a like view as seen from theoppositeor inner side, with the main or carrying wheel dotted in place. Fig. 3is a view inrear elevation. Figs. 4 to 10, inclusive, aredetail views.Of these views Fig.4 is an inside elevation, showing the heel of thetongue, the

'vertically-adjustable bracket with which the axle of the carrying-wheelconnects, a partof the wheel adjusting or leveling lever, aportion ofthe plow-beam, and the clip-fastening secured thereto. Fig. 5 is a view,partly in rear elevation and partly in section, on the line 5 5 of Fig.4. Fig. 6 is a view, partly in elevation as seen from the inner side andpartly in section on the line 6 6 of Fig. 5; Fig. 7, a view, partly inside elevation and partly in section,

. showing the connections between the levelinglever and its detent, andan adj usting-bar which has connection with the axle of thecarryingwheel. Fig. 8 shows the rolling colter and its connection withthe beam. Fig. 9 is'a view, partly in elevation and partly in section,showing the seat-supporting spring and its adj usta- V ble connectionwith the adjusting-bar. Fig.

10 is a view, partly in section, of the jointer or detachable auxiliarymold-board, the clearer-rod or.weed-turner, and their fastening devices.Figs. 11 andl2 show, respectively, a

rear elevation and a view partly in elevation as seen from the innerside, and partly in secits connections.

The beam A, the clevis a, the rollingcutter B, adj ustably secured inplace by its shank B, and the clip-bracket b and eyebolt b,are all ofsuitable well-known construction. The plow wardly or toward themold-board side, and

slightly forwardly at its upper end. (See Figs. 1 and 2.) In this'wayweeds, &c., are prevented from accumulating against the cutter andbeneath the beam to an extent sufficient to injuriously clog the plow,the curvature of tion, of a modification of the clip-fastening and I thecutterrendering it selfclearing by turning and deflecting the trash tothe side; i The cutter is formed to constitute the landside G, and alsoserves as a means of attaching a weed turner or clearer, D, and ajointer or small auxiliary mold-board, E. Bolts 6 e and nuts passthrough holes in the cutter and in the jointer-back or attaching -plate,as well as through a slot or loop, d,'of the clearer-rod. The samefastenings thus secure both the clearer and .the jointer. A series ofholes in the cutter 0 provides for vertical adjustment of the clearerand jointer, so as to adapt them to operate to the best advantage,whether the.

plow is cutting a deep or shallow furrow. 'As will readily be seen, thej ointer serves-t0 turn the, edge of the furrow-slicenext the landbefore the turning over of the slice by the mold-board D. The result isthat the plowed ground is left smoother, because the turnedunder edge ofthe oiie slice abuts against or is presented close to theedge oftheslice to which it is contiguous, instead of overlapping it. The jointer protects the threaded ends of the fastening-bolts and their nuts,it will be seen.

Handles may beprovided, so that the plow may be used either with orwithout the hereinafter described riding attachment.

The beam is provided with aclip-fastening,

' which by preference is composed of outer and This clip-fasteningserves as a means for jointing to the beam the axle G of a mainsupporting or carrying wheel, G, for making a hinged connection betweenthe beam and the tongue, and for jointing a leveling-lever, H, in placeupon the beam, as next in turn to be explained.

The inner clip-plate, F, is provided with a guideway, as clearly shownby the drawings, for a vertically-adjustable eye-piece or socket slide,with which the hooked end of the axle connects. A securing bolt and nut,g, and a slot, 9, in the plate VF, provide for adjusting and clampingthe slide 9 in place.

A metallic heel strap or plate, I, is secured to the tongue and inclinesdownwardly therefrom. A socket, i, is provided at the rear end of thisheel-strap. A bolt, 1, passes through this socket and through the upperends of the clip-plates, so as to pivot these parts together. The bolt 1serves also to joint the lever H in place, as well as to secure one endof a curved brace-rod, H, the opposite end of which is connected by abolt, 72, Figs. 1 and 3, with the p in hearings in the lever andbracket.

opening made through the trunnions of the lever above its jointedsupport. A second heel-strap, J, secured to the tongue, is connectedwith the lever H by a bolt, 71. The bolts h h and their nuts serve toattach a loopbraoket, J, to the back of the lever.

A rocking guideway or transversely-perforated roller, j, is mounted byhollow trunnions The rocking guideway extends entirely through it,intersecting the transverse or guideway opening. A spring-actuateddetent-lever, K, is, provided with a lug or bent end, k, to enter thetrunnion-opening and cross the intersecting or guideway opening. Thedetent-lever is pivoted to the leveling-lever H, and it may be movedagainst the force of its spring in obvious ways and for a purpose now tobe described.

A 'perforated adjusting-bar, L, adapted to slide in theguideway-opening, is held in any desired position by the detent-lugJc,engaging with its perforations. This bar Lhas a vertically adjustableand jointed connection with a post or upright standard, L, which isrigidly united with the axle 9 near the carrying-wheel. The upper end ofthe standard is forked or slotted and perforated, (see Figs. 2 and 3,)and the adj usting-bar is secured at any desired elevated between theforks of the standard by a bolt, Z, passing through perforations in thestandard and the adjusting-bar. The bolt is secured by a nut at the backof the standard, and is provided with an eye, Z, at its opposite end fora purpose to be explained farther 011. It will be seen that by means ofthe leveling-lever and its detent the adjusting-bar and its verticallyadjustable connection with the base of the standard L. c is jointedby'the eyebolt Z Z to the axle-standaxle-standard, and the verticallyadjustable connection of the axle with the clip-fastening on the beamthe carrying-wheel may readilybe leveled or adjusted up or downrelatively to the plow to suit the depth of plowing, and so as to keepthe adjusting-bar level. ,7 The adjusting-bar is over and parallel, ornearly so, with the axle. It supports the drivers seat M, and it istherefore important that it be maintained level, or nearly so, and insuch position as to locate the drivers weight about over the axle. Theseat is. adjustable lengthwise of the adj Listing-bar, so that more orless of the drivers weight may be brought upon theplow, according to thenature of the soil, the depth to which it is desired to plow, &c. Toprovide for adjusting the seat its supporting-spring M is secured to aslideblock, lVP, (best shown by Fig. 9,) which is provided with across-shaped or T-groove to fit about the adjusting-bar and its frontand rear ribs, m m. A set-screw, m, serves to clamp the slide-block inplace and hold the seat in the desired position. a

The axle is held against backward swing by being connected with thetongue in the following way: A downwardly-projecting side arm, N,fastened to the tongue, is provided with a swiveling eyebolt, n, whichmay be adjusted by its nuts 12 n, so as to cause it to project more orless to the rear. A link-rod, N, is jointed at its front end with theswiveling eyebolt'n, and at its rear end is similarly jointed by theswivel-bolt O to the axle, at or near the A brace link-rod, P,

ard at one end, and at its opposite end is jointed to an adjustabletubular eye-block, 0, adapted to slide 011 the rod N, and secured in thedesired position by a set-screw, p. v

ltwill be seen that by adjusting the swivelbolts n and O the connectionbetween the axle and the arm N- may be lengthened or shortened, and thatvariations in the position of no the eyebolt Z Z, caused by adjustingthe connection between the bar L and standard L, may be compensated bysliding the tubular block 0 along the rod N, thus preventing thecramping of the brace-rod P.

The plow is raised or lowered and the depth of plowing regulated byrocking the beam about its hinged connection with the tongue may workthe'lever by both foot and hand. A

chain, R, connected with the beam-adjusting lever passes over a pulley,1-, supported on the tongue about over the clevis pivot-bolt, and isattached to the beam by means of an eye, 9', of this bolt.

The team being hitched to the clevis in the usual way, the operation ofthe beam-adj usting 'devices in regulating the depth of plowing willreadily be understood, and it will also be seen that the adjusting-levermay be rocked back far enough to lift the front end of the beam to anextent sufficient to raise the plow clear of the ground, so that it canbe transported on the heel-roller and the carryingwheel.

In order that the plow may give slightly by vibration of the beam to oneside or the other independently of the tongue when encountering stones,stumps, &c., which tend to deflect the plow from its course, and torelieve the tongue of unnecessarylateral strain, the modification of theclip-fastening and its connections (shown by Figs. 11 and 12) may bee1nployed in lieu of the before-described vertical clip-plates RF, theupper and lower bolts, f f, and the bolt I. passing through the socketof the heel-strap and serving to secure the leveling-lever in place. Asmodified the levelinglever H is forked at its lower end, and its forks s8 rest upon a clip-plate, T, on top of the beam. A clip-plate, T,beneath the beam is connected with the upper plate and the two platessecured to the beam by vertical bolts t t and their nuts. The bolts alsosecure a plate, t,-upon the top clip-plate. The plate t is pro videdwith a loop or eye, 8, which is engaged by a rearwardly-projecting hook,S, detachably' connected by its shank with the levelinglever, at thejuncture of its fork, by a bolt and nut. A forwardly-projecting hook oreye, S, on the same shank as the hook S, serves to OQllnect with a hook,U, of the downwardly-inclined heel-strap of the tongue. To provide forthe attachment of the adjustable socketslide 9 the upper clip-plate ismade'of angular form and the slide secured to the downwardlyprojectingside a, in the manner before described with reference to. the side plateF. 7

It will be seen that j the lever-forks s s and the loosely-interhookedloop 8 and hook S .fore set forth.
